This invention relates to improvements in the construction and operationof supporting brackets in combination with a head bar for Venetianblinds and the like. a

An important object of the invention is the provision in combinationwith the head bar of a Venetian blind or the like, of a bracket forsupporting the head bar and limiting the longitudinal movement betweensaid head bar and bracket.

Other objects of my invention will either become apparent or bespecifically referred to in the following description thereof wherereference is made to the accompanying drawing, and in which Figure 1shows the upper left-hand corner of a Venetian blind as the same wouldappear when equipped with and mounted in my improved bracket and headbar. It will be understood that two such brackets are used in supportingthe head 20 bar, one located at each end of the head bar. Inasmuch asthe brackets are similar in construction except that one may bedescribed as a lefthand bracket as distimguished from a right-handbracket, it is believed that an illustration of one of the brackets incombination with the head bar will be sufficient for anyone skilled inthe art to understand my invention. I

Figure 2 shows an elevational view of the head bar and bracket shown inFigure 1.

Figure 3 is a sectional view taken on line 3-8 of Figure 2 and lookingin the direction of the arrows.

Figure 4 is a plan view as seen from the top of Figure 2. v

Figure. 5 is a development of a piece of sheet metal from which, bymeans of a series of bending operations, my improved bracket may beformed.

Figures 6, 7 and 8 show details of the bracket formed from thedevelopment shown in Figure 5.

Figure 9 is a perspective view of the left-hand end of the head barshown in Figure 1.

Referring now to the drawing, it will be seen that a head bar 10 issupported at the upper part of a window in a bracket 11. The bracket 11is formed from a single sheet metal stamping comprising a side 12 and aback 13 bent at right angles to each other. Screw holes 14 arepreferably formed in either or both the side 12 and back 13 to providemeans for mounting the bracket in any suitable position. A front 15, atop 16 and a bottom 17 all cut integrally from the same piece of metalas the side 12, see Figure 5, are bent along the dotted lines shown insaid figure in the same direction as the back 13 and at right angles tothe side 12. It will be understood that the back, front and bottom form,in effect, a socket into which the end of the head bar will freely fitand may be longitudinallyadjusted with respect to the bracket. A lockingtoggle 18, formed integrally with the back 13 and on the edge thereofremote from that at which it joins the side 12, is bent at right anglesto the back and toward the front 15, see Figure 8. If desired, screwholes 14 may also be formed-in the top 16.

The head bar 10 of the blind comprises a web 20 having upwardlyextending walls 21 and inwardly extending flanges 22 formed thereon bybending the upper edges of the walls toward one another. A screw slot23, in the front wall 21 and an elongated opening 24 in the rear wall21, are formed at the left-hand end of the head bar.

' The bracket 11 and head bar 10, as shown in Figures '7 and 9, may beassembled as shown in Figure 2 by lifting the left-hand end of the rearwall of the head bar upwardly through theclearance space 25 locatedbetween the front 15 and the bottom 17 and into engagement with thebracket; and thereafter sliding the head bar toward the back 13 of thebracket so that the locking tongue 18 projects through the opening 24and the slot 23 is disposed over one of the screw holes 26 in the front15 and the end of the bar rests on the bottom 17, see Figures 3 and 4.When the screw 271s secured in place, but not tightened, it will beunderstood that the bracket 'may be adjusted longitudinally on the headbar an amount equal to the length of the opening 24 and that a greateradjustment is prevented by the engagement of the tongue 18 withthe endsof the opening 24.

It will be understood that the bracket and head bar constructionemployed at the right-hand end of the bar, not shown, is similar to thatJust described with the result thatwhen the brackets are securelyfastened to the window as shown in Figure 1, the blind may bev securedin place by simultaneously elevating the rear wall and the flange of thehead bar into position above the bottom piece 1'7 and then pushing thebar into place against the back piece 13. Thereafter any suitablelongitudinal adjustment of the bar may be made with respect to thebrackets to position the'blind centrally of the window. In a device ofthis kind the locking tongue 18, projecting as it does across the mouthof the socket, prevents the brackets and head bar 19 from beingassembled when the brackets are mounted at a I distance from one anothergreater than that which would permit the bar to be securely supported bythe bracket, because the opening 24 is disposed close to the end of'thebar. Further,

if the brackets are mounted too far apart and one end of a head bar isproperly assembled in a bracket, it becomes impossible, becauseof thelocking tongue 18, to pull the assembled end of the head bar out of thebracket in an effort to support the otherend of the bar on the otherbracket. Hence the combination of a head bar and locking bracket of thiskind prevents injury to a person attempting to install a Venetian blindwhen the brackets are not properly mounted and spaced with respect toone another.

This bracket and head bar combination is also illustrated and describedin my copending applicationSer. No. 726,223, filed May 18, 1934.

While I have described what seems now to. be the preferred embodiment ofmy invention, it is conceivable that various modifications in theconfiguration, composition and disposition of the component elementsgoing to make up the same as a whole, as well as in the selectivecombination and application of the respectiveelements may occur to thoseskilled in the art, and no limitation is intended by the phraseology ofthe foregoing description or illustrations in the accompanying drawing.

What is claimed is:

1. A Venetian blind bracket comprising means forming a socket in which ahead bar is adapted to freely fit, in combination with a locking tonguedisposed transversely across the mouth of the socket to prevent theinsertion into or withdrawal therefrom of a head bar by a longitudinalmovement with respect to said bracket.

2. A Venetian blind bracket comprising a side; and a back, a front, anda bottom all secured to said side and forming a socket in which a headbar is adapted to freely fit; in combination with a locking tonguespaced from the side and projecting transversely, of the mouth of thesocket.

3. A Venetian blind head bar formed with an elongated opening proximatean end thereof, in

combination with a bracket for supporting the end of said bar in whichis formed the opening aforesaid, said bracket comprising a bottom and alocking tongue extending transversely of the bottom for projecting intothe opening in said head bar.

4. A Venetian blind head bar formed with elongated opening proximate anend thereof, in

combination with a bracket for supporting that, end of said bar in whichis formed the opening aforesaid, said bracket comprising a bottom, a,front, a back, and means for mounting the same with respect toone'another to form a socket for receiving the end of said head bar, anda locking tongue extending transversely of the mouth oi! said socket,said tongue and opening forming means to limit the longitudinal movementbetween the head bar and the bracket.

5. A Venetian blind head bar formed with an elongated opening proximatean end thereof, in combination with a bracket for supporting that end ofsaid bar in which is formed the opening aforesaid; said bracketcomprising a bottom, a

front, a back, and means for mounting the same bracket, said stampingcomprising a side, a front,

a back, and a bottom forming integrally with said stamping, said backcomprising a locking tongue formed integrally therewith and projectingin spaced'relationship with respect to said side toward said front, saidtongue and opening forming means to limit the longitudinal movementbetween said head bar and bracket.
